And you know how big and how much material that 'core area' is,
despite no one ever having built a working power fusion reactor?

Even without knowing how big the the core area is, or what materials
it is made from - we do know that fusion reactions produce neutrons.

It doesn't matter how big it is, the 'core' will be bombarded with
neutrons.

It doesn't matter what material it is made of, the 'core' will be
bombarded with neutrons.

Regardless of size, or material, it's going to be subject to neutron
activation.

Wow, I'm IMPRESSED. You should go tell all the researchers about
this. It might help them out.

The researchers know it already, read the dismantlement and disposal
plans for ITER for example.

Oh, and the same thing is essentially true of fission reactors. All
you have to do is use a primary coolant with a low neutron cross
section. All the world ain't PWRs, you know.

The issue is completely different with fission reactors - which use
highly radioactive fuel which produces radioactive waste at every step
of the chain, which fusion reactors don't do.
